Introduction to the instruments used for chemical filtration of sodium sulfide manufacturer
Filtration is a kind of operation of separating solid particles suspended in liquid or gas. Many equipment are used for filtration. Here, several common instruments are mainly introduced here, for the reference of producers only.
(1) Tube filter
It is composed of porous filter tube, easy for insulation and filtration, and is used to purify very fine impurities in the filtrate, such as capacitor borax, barium carbonate, etc.
(2) Three-legged centrifuge
Forming products. Smooth operation, small footprint, easy to control the separation and washing time, but long filtration cycle, small production capacity, high labor intensity. For the crystalline separation of inorganic salts, such as copper sulfate, sodium red alum, etc.
(3) Taper-type continuous centrifuge
Formed products, continuous filtration, unloading, simple structure, convenient maintenance, but washing is not good, the filter slurry is small solid ratio, large leakage, suitable for the separation of large particles uniform crystallization, such as borax.
(4) Spiral unloading settlement centrifuge
Continuous filtration, filter cake can be washed, the filtrate contains 1-7%, suitable for the separation of large changes, large difference of suspension, there are vertical and horizontal. For the filtration of calcium carbonate and nickel sulfate.
